The Zheng family proudly welcomed their first-born child, a son, Matthew, into the world on October 2, 2014. After his birth, doctors found a defect in Matthew’s heart. He was diagnosed with Tetralogy of Fallot (TOF), a rare congenital heart defect and high lung pressure. Despite his diagnosis, the doctors thought Matthew’s heart was strong and surgery was not necessary at that time. Unfortunately, that was not the case; and two weeks later Matthew was rushed to the hospital after he began turning blue.
